I would hope that even a youngster like Rusty would know that a mask left in the woods for about 20 years would not be in very good condition. Okay, so it must have been recently left. The pink crystals seem to tie in to Rusty’s Tadd Crass hypothesis, aided by Cherry’s good memory of commercials.

But I have to admit that I have not figured out how Mark connects all of this to the notion of an injured camper. Would the suspicious light then have been some kind of rescue signal? Or maybe some aliens actually did come down during the night (as they always seem to do), kidnapped the camping Tadd Crass (as they always seem to do), and are now probing him and dissecting him for evil reasons (as they also seem to want to do). The alien ship could also have made that curious incision around the campfire.

Or maybe it was just Doc Davis, apparently a fan of that old show, who put all this together to prank his own family for leaving him out of all of the get-togethers.
